The area I had earlier marked in river sand was dug up. But since the roots of the coconut tree are too tough to be entirely removed [soil too is clayey a bit], I've decided to shift it a little bit into a bean shape. Digging is still on, with yours truly doing all the work after the above woodcutter did his job which was just half to what I wanted. Now I've to give a shape with different levels inside the pond, by adding some moist earth and shaping it up. I'll give the entire area a mud plastering to make the tiny roots stay back to prevent piercing the liner and have a smoother finish.

There are some roots growing in the direction of the pond that was cut , but it may regrow its smaller branches later. How to prevent this and avoid future damage to the liner? These are about 1 cm in diameter. I cannot remove the entire root as this is from a Copper pod tree 50 feet away, in the next premise, across the road!
